Subject: [PATCH net-next 6/9] selftests: mlxsw: Add a scale test for RIF MAC profiles
From: Danielle Ratson <danieller@...dia.com>
Query the maximum number of supported RIF MAC profiles using
devlink-resource and verify that all available MAC profiles can be utilized
and that an error is generated when user space tries to exceed this number.
Output example in Spectrum-2:
$ TESTS='rif_mac_profile' ./resource_scale.sh
TEST: 'rif_mac_profile' 4 [ OK ]
TEST: 'rif_mac_profile' overflow 5 [ OK ]
